GHRP-2 (Growth Hormone Releasing Peptide-2) is a synthetic hexapeptide widely studied for its ability to stimulate the natural release of growth hormone through endocrine signaling pathways. As part of the growth hormone secretagogue (GHS) family, GHRP-2 acts primarily by activating the growth hormone secretagogue receptor (GHS-R), also known as the ghrelin receptor, which plays a central role in regulating hormone secretion and metabolic signaling.
